Michael Buble can add acting chops to his resume ... 'cause the beloved crooner pulled a cruel, cold-blooded and HYSTERICAL prank on one of our photogs!
We spotted the singer walking around Bev Hills, and asked him about fellow singer Josh Groban possibly replacing Michael Strahan on 'Live.' Buble was NOT in the mood to talk ... or so it appeared.
The video is so awesome ... it almost makes up for Buble's recent corn on the cob fiasco, which he tried to explain away to our guy.
